The issue of consolidator fares, esp to Asia, has come up a number of times, on this forum. The question most frequently asked is which travel agents, deal with consolidator fares.

I am now asking a different question. Which airlines that fly from Canada to international destinations, offer consolidator fares. I would guess, perhaps incorrectly, that AC does not offer consolidator fares, and no consolidator fares can be obtained through any US airline (whereby one would have to take a transborder flight, first). I would guess that many Asiatic and European airlines do offer consolidator fares?
